Here’s someone asking for an implementation of DragonFly’s swapcache, for Postgres. The response, quite correctly, is “No.” I can’t imagine how painful it would be to support a database-specific disk caching system across multiple platforms, on top of whatever each platform did on its own. (Thanks, Jan Lentfer)

Your unrelated comics link of the week: Friends With Boys. The whole comic is available online starting with the first page here and going on for about 200 more. The full comic is only going to be online for a few days – hopefully enough for people to see it – and then you have to buy it. (There will still be a preview.) It’s a good story.
